About the character encoding problem my database (mysql database software) uses utf8 and each table in it is also utf8 and the type of general_ci; & nbsp; my php editor uses the UTF-8 encoding method. The browser also uses the UTF-8 encoding method. after operations on the webpage, the browser submits the code to the database through php, the data in the database is about character encoding.
My database (mysql database software) uses utf8 and each table in it is also utf8 and the type of general_ci;
My php editor uses UTF-8 encoding;
The browser also uses UTF-8;

After the operation on the web page is submitted to the database through php, the data in the database becomes garbled "å ½ ± §? Å ¨ ±ä¹ "(similar to this garbled code)

In addition, inputting normal encoding data in the database is also garbled when it is displayed in the browser.

I don't know what the problem is. At first I had a problem with the thinkphp template, but I connected the database and operated it with the original (self-written, there is still a garbled problem...

I don't know what's going on with you, but I have never encountered any problems using the following methods:
1. set the character set of the database to utf8
2. when connecting to the database, use mysql_set_charset ('utf8') or set the character set during connection.
3. set the text character set of the editor to utf8.
4. set the http header content-type = text/html; charset = utf-8

Hope to help you
